Reimplement outer rounds as "compact" in x86 assembler. This has rather · af8c1d81

strong impact on decrypt performance, 20-25%. One probably should consider
switching between slower and faster routines depending on how much data
we were asked to process.

Mitigate cache-timing attack in CBC mode. This is done by implementing · c8d5c71a

Andy Polyakov authored Apr 16, 2005

compressed tables (2x compression factor) and by pre-fetching them into
processor cache prior every CBC en-/decryption pass. One can argue why
just CBC? Well, it's commonly used mode in real-life applications and
API allows us to amortize the prefetch costs for larger data chunks...
